Do many of you use your PJ as a tv replacement? Im concerned about how long these expensive bulbs will last in everyday use. If youre lucky, I guess 2000-3000 hrs would last 12 - 18 months with typical daily usage but then youre looking at £300+ for a replacement. By this time the PJ may well have depreciated to the point where its not cost effective to actually replace the bulb. I know the ae700 claims 5000 hrs but with the ever-growing number of reports of VB problems, buying this PJ is beginning to sound like a lottery. The Z3 sounds like a promising alternative but with the bulb only covered for 90 days & Sanyo unwilling to state the life expectancy, Im reluctant to commit.
